SHIP cons'rnuctrio v.

Beit known that I, JAMES asubject of the King of England, residing at 4-3 Highfield south, Rock Ferry, in the county of Chester, England, have invented a new and useful Improved Ship "Construction, of which the following is a specifica tion.

This invention has referenceto the construction of parts of the internal structure of ships, and means .for obtaining access to and egress .from the tween' decks and holds of same; and thestructure according to it is such, that it serves as a part of the means for supporting the-decks from the tank top or bottom of the ship, namely, as avpillar used between the decks,and as means for gaining accessto and egressfrom the spaces or chambers between the different decks, or some of them, and the lowerholds; and other uses hereinafter described; These combined pillars and access and egress means are preferably ,made. ofsteel or iron plates of relatively large size, and of rectanglar,

cylindrical, triangular or other suitable form; so that a man can pass up and down within them; and they-are provided or fitted with rungs or ladder parts, so that men,

can climb up" them from one deckto an-. other, and from the bottom of the ship'to the top; and-from all of them, to the upper deck of all. And they are built into the decks, or floor and decks, so that they serve as some of the pillars of the ships structure, in addition tov their being a'means of access and egress, and occupy the space in the interior of the hold,0f the ordinary pillars, which would ordinarily not-be available for use. By this invention, therefore, little or no materialspace is taken ofi the available tween-deck and hold capacity for the storage of cargo, and sono loss of cargo space is occasioned by the application of the invention, nor diminution of structural strength. In some cases, one, two or more sides or parts of this ladder-pillar is or are open for purposes hereinafter described; and in some cases the ladder rungs are fixed in the interiorof pillar, for the whole or part of its length, or formpor-x tions of it; while in other cases the rungs or ladder lengths are movable or portable, and fitted in it.

The invention is'illustrated in the accompanying drawings, in which Figure 1 is an elevation showing one ap- Specificatio'n of ietters Patent.

Referring now :to thedrawings', and more particularly to Figs. 31,- 2,. and 3, a is the tank top at ythebottom:ofjthe ship; Z) repre-F sents the main deck of-the ship; and c the "upper deck; dqrepresents the girders and coamings aroundthe hatchways in the decks 0 and Z2; and care the deckbeams extending between the side girders dfof the hatchway' y, and the sides ofthe ship. The pillars jextendingbetween the bottom 'a'and decks b 'and'o are generally'designated a; and they are disposed inthe usual .positions above described in relation to the longitudinal girders forming partof the sides of the hatchway y, and tothe deck beams ;e.. The

pillar or pillars a'ccordingto this invention,

may be any one (or more) that may be most convenient; and 1t maybe-assumed that one of the four shown in the plan in Fig. 4 is accordingto the invention. "At the lower end, the ladder-pillar z, is built into the tank top a of the ship; and in this tank top, a manhole a is provided, andis normally firmly closed by a manh'ole cover; but by removing the cover, access is had to the interior of the tanks or bottom of the ship 0,

for gainlng access to it for passing a hose" I or pipe down into it, by way of-the: pillar a or, other purpose. The top" of thislower portion of the ladder-pillar is, built into the plate 7 connected with the bottom of the hatchway girder d,-Ithis plate being carried a toward the sideofthe ship" some distance as shown, and connectedjalso with two of the deckbeams e by-theplate structure 9,

in the well known way. The plate f has an opening f in it for passing up and down, which coincides vertically with the top of the pillar z.

The bottom of the ladder-pillar extending ing in it. Above this pillar and an opening 0, in the upper deck 0, there is a tubular structure c',.serv1ng as a ventilator coamlng; and through this tube or coamlng 6, access is had to the ladder-pillar below; and this i :ablythat shown inthe drawings.

access can be'had at all times, to the pillar from top to bottom; and thereby to the tween-deck, or "tweendecks, lower hold, and

to the ballast tanks. The tube or coaming I 2' may,- instead of serving for a ventilator base,.serve the purpose of a Samson post, orvif desired it may be extended up to form a platform or base for a derrick. When fitted with a removable ventilator cowl, the

; pillar and cowl themselves are adapted to serve as a ventilating meansto the holds or spaces below. I I g The ladder portions within the pillars z are marked Z, and their'position is prefen They may be of any suitable construction, with side bars, and rungs of metal, such as are commonly used in ships. The pillarsz, in the case shown, are rectangular in form, and

they are made of plating on three sides,

which closethese sides; while at the fourth side there are open parts; and the two inturned corner portions of theplating referred to, are connected together by straps or plates 70. The side, as the drawing shows, is away from the'openin g of the hatchway, and toward the sides of the ship or bulkheads, One of these plates 76 is always fitted and used at the bottom of the lengths of pillars, where they-are built into the deck, so asto form a coaming or closure to the pillars at the lower parts. Also, a plate 72 is used at the top of the pillars, while between these, intermediate strap plates is are arranged at intervals, as shown. Through the openings between these straps or die bars 70,

man can pass into or out of the cargo space in the various parts of the ship.

A As shown in Fig. 3, the interior of the ladder pillar. at one or more parts or sections, is provided with internal channels mor the like adapted to receive and have fitted in them boards, plates or the like for closing the opening or openings of the pillars; so that when the vessel is carrying initshold or spaceycereals, coal, ore, or other cargo in bulk, it is prevented from gettinginto the interior of the pillars. Inthe case where the tube or coaming 2' forms a derrick plat form or box, or a samson post, one or more openings may be formed inits side or sides,

for the purpose of gaining ingress into, and

egress from the h lds, chambers, or spaces below; and it may have grips or rungs on its inside for enabling the users to climb up and ClOWIlxll'l it; or, if desired, the entrance to the tube, may be solely through the upper open top of this coaming or tube 2'. The outside of the pillars may be fitted or provided with battens or guards of any suitable material, to prevent cargo being chafed or damaged if it should come into contact with the material forming the pillar; and the interior of the pillar can be fitted with pipes to serve as air pipes, sounding pipes,

steam injecting pipes fire indicator plpes or for other purposes. In the case shown, the

pillar" is made largely of-metal plates or plating; but in others it may be made of a plurality of vertical stanchions or bars of sectionmetal. lVhat isclaimed is In a ship, the combinationof hatchways, decks with apertures in proximity to the hatchways, deck beams attached thereto, plate structures connected with the deck beams, plates with apertures attached to the structures with the apertures disposed beneath the apertures in the decks, hollow supporting pillars disposed in line with the said apertures and attached to the said decks and plates, ladders disposed within the hollow pillars for enabling a person to passup and down the pillars and through the said apertures, and means for entering and passing out of the hollow pillars.

In testimonywhereof I have signed my "name to this specification in the presence of two subscribing witnesses.
